Messrs. Veitch of Exeter received this really handsome Bramble 
from Nepaul, and cultivated it for some time under the name of 
R. leucodermis, a name it well deserves, from the pure white of 
the stems of the plant, looking exactly as if they had been white- 
washed. Closely examined, the cuticle is found covered by an 
extremely minute, perfectly white, pulverulent substance. The 
name however of Jeucodermis is given by Mr. Douglas to a 
North-west American species, and adopted by Messrs. Torrey 
and Gray in their ‘Flora of North America,’ which species we 
have been ourselves led to consider a variety of Rubus occiden- 
falis of Linneus. Our plant is identical with a Nepaulese and 
Himalayan species in our Herbarium, which we believe to be 
_the R. biforus of Dr. Buchanan (Hamilton), and probably the 
R. pedunculosus of Don. It is quite hardy and ornamental, and
